1161If you are aware of making FBD then draw the FBD for the block and and wedge separately and then try to write Force balance equation and finally solve that equation.
11If you consider the FBD of the small block:
mgsinC-T=ma(where a is the acceleration of the small block and subsequently the wedge.)
or, T=mgsinC-ma
If we consider the FBD of the wedge:
T-TcosC+mgsinCcosC=Ma
By replacing the value of T we get:
mgsinC-ma-mgsinCcosC+macosC+mgsinCcosC=Ma
By solving we get:
a(acceleration)=mgsinCM+m-mcosC(Ans.)
- Anik Chatterjee i dont think that acc. of wedge=acc. of small block..
i think it must be acc of block=(acc of wedge)sinCUpvote·0· Reply ·2013-05-29 01:56:38
- Akash Anand Acc. of block and acc. of wedge will be different. Acc. of block will have an acceleration down the inclined along with in horizontal direction as well.
